We ran out of gas home, so I decided to jump into the car and drive to Musoma to get a refill (which means bringing back an empty cylinder to a dealer and getting a full one, paying 45,000 Tanzanian shillings). To my taste and to my parochial budget, the retail price of the gas is way too expensive for any average customer in Tanzania. This gas cylinder will last for a month, sometimes bit longer, sometimes bit shorter. At the same time one sack of charcoal in our area is still around 8-10 thousand Tanzanian shillings. I will use maybe two sacks per month. You do the counting.
